 note = {Purpose : Mouthguards (MGs) are generally fabricated by heating and molding ethylene-vinyl acetate (EVA) sheets. In this study, we investigated the change in hardness of EVA material by heat-molding MGs. 
Methods : Five different EVA sheets were heat-molded on the model to produce MGs. The anterior and molar regions of MGs were cut out for sampling materials. A micro durometer (MD-1, Kobunshi Keiki Co Ltd, Kyoto, Japan) was used to measure the material hardness.
Results : In most samples, their hardness rose after heat-molding, and the hardness level was higher in anterior regions than in molar regions.
Conclusion : The hardness of EVA used in MG materials tended to increase after heat-molding., 10.15090/00013766},
